1 EGO: Everyone s Gliding Observatories Pierre Testor LOCEAN, CNRS, Paris, France The Economist, 2012/06/09 OCG-5, September 2013

2 EGO: gliders capabilities Land Station Data Centers Scientific/ operational community, users Scale interactions global scale Regional scale seasonal mesoscale ~2-5km 1km Processes submesoscale Maneuverable ; U ~ 25km/day ; a dive in ~0.5-5h (1-2 vertical profiles) Physical and biogeochemical sensors (ECV/EOV: T, S, O2, ADCP, fluo Chl, fluo CDOM, optical backscatters, nitrates, hydrophones, ) + average currents over the dives Versatile and reusable OCG5 - September 2013 high spatial and temporal resolution profiles during (~2-4 < 11) months real time data for operational models and process studies (global, regional and coastal) Emergency/environmental response

Gliders can be used in combination with the other components of the GOOS (Satellites, OceanSites, Argo, ) enhance the spatio-temporal sampling of the GOOS (in-situ) where required. (reduce uncertainties due to small scale processes ; coverage in coastal/marginal/regional seas, water formation sites, biogeochemical provinces, western and eastern boundary regions, straits) OCG5 - September 2013

5 EGO: requirements-setting process/es OceanObs 09 recommendations: the formation of the global glider system; the adoption of standards and a Argo like data system for gliders; the target of ~20 standard lines in the next 5 years and then, more; the setup of a network of shared resources and expertise; to distinguish between climate and process and NWP objectives; to establish the adoption of a common and accessible portal for glider data. Development in the framework of 3 main research communities: USA: IOOS - NGN Australia: IMOS - ANFOG EU: COST Action ES EGO (coordination/wide-open: include Australia, South Africa, Israel, Mexico, Canada, Peru, Chile, ) FP7 Research Infrastructure design study GROOM Gliders for Research, Ocean Observation and Management (WP2 Integration into the GOOS)

6 EGO: issues and challenges Two-way communication system (pilots!) Expertise required (gliderports = communication and computer resources, workshops for maintenance and development, pools of gliders, sea-access) Numerous operators and distributed facilities Map of main gliderports

7 EGO: issues and challenges best practices for gliders! the formation of the global glider system; the adoption of standards and a Argo like data system for gliders; the setup of a network of shared resources and expertise; to establish the adoption of a common and accessible portal for glider data.

9 EGO: issues and challenges Process studies AND long-term observations Monitoring the glider network activity is based on the operators good will. Maybe ~500,000 profiles since A lot of data sent to data centers but All glider deployments since 2005 (+ deployments in the Artic/Antarctic, SE/SW Pacific, Polynesia, Indian ocean, ) USA ~ 12,000 km altitude EU AU

10 EGO: issues and challenges All platforms the data flow is interrupted somewhere! data during 3 months (April- June 2013) from no glider data at all during the last month! Gliders Last month glider data at Coriolis > 11 gliders in the water OCG5 - September 2013

11 EGO: issues and challenges Just in-between pilot and mature networks. The integration of gliders (as platforms) is nearly done - just the last steps glider officer/coordinator position to open? Support for deployments/recoveries (coordination for ships opportunities, ) monitoring the network downstream the glider operators/communities voice/advocacy in international panels ½ position? To be shared with regional/coastal coordination purposes? Maritime law/traffic issues No global glider-specific program yet ( only a superposition of projects, some/few of which are long term observations) - although straightforward for marginal seas (EEZs) versatility = a strength and a weakness Sustainability of the network? Consolidate the international EGO scientific network after the end of the COST Action ES0904 EGO (July 2014) Consolidate the network of gliderports for a better range OCG5 - September 2013

12 EGO: strategy for evolution of observing system/sensors Network evolution fill the gaps! Common data format/standards Capacity building: develop the network (coastal/regional and global scales) GOOS/GRA/ROOS endorsement to leverage funds and foster collaboration with the other components Discussions on a global and gliderspecific program (trade-off regional/global?) scale arguments and OSSEs Hardware evolution : New sensors (also relevant for Bio-Argo, marine meteorology) Better endurance (1 year?) Deep (6km) gliders (cross-basin sections WOCE 2.0 ) Wavegliders (ASVs)?

13 EGO: integration across networks Data management (RT and DM) and technical coordination for physical and biogeochemical data/sensors (Argo/OceanSites models) Two-way communications paradigm (is EGO a model?) - messengers How far? Links/complementarities with other components (solve coverage issues ; cross-calibration, ) - a GOOS glider project and/or the glider sides of GOOS projects? Satellites Variability around moorings Between Argo floats (300km, 10 days) Around R/Vs (Testor et al, 2010 CWP) EGO/GROOM artistic view

14 EGO: desired outcomes from participation in JCOMM / OCG? Ecosystem services/biology CBD CSD WSSD Weather & Climate UNFCCC/IPCC WCRP Real-time services Emergency support Ocean forecasting Fisheries FAO Regional Regional seas MSFD CCAMLR Assessments Global Marine (UN) TWAP (GEF) Regional Endorsement, visibility and more outreach/awareness Issues impact Data products sustainability and capacity building Help to solve the maritime law/traffic issues Data Assembly Issues Requirements Essential Ocean Variables ArgoSOOP IMOS IOOS Satellite Issues Requirements Expanded EOVs Expanded observing systems and networks Better use of glider data (e.g. in-situ/satellite comparisons, models, ) Better coordination with the other in-situ components Snowball effect for (future) glider operators Gliders VOS in the loop! Definition of a global glider program ; consensus on main scientific objectives
